When most people hear the word “durability” in relation to wood, they immediately think of its ability to withstand dents and scrapes. However, in this context it specifically refers to a wood’s ability to resist elemental and natural forces of decay. (The former notion of durability equating to physical toughness would be better explored through Janka hardness and Modulus of Rupture values.)

Degradation of wood can occur from fungus (caused by cycles of rain/moisture), or from termites or other boring/destructive insects. An overall chart defining the terms used to describe a wood’s durability in direct ground contact:


 Classification Service Life (in years)  Wood species
 Very Durable 50+  Bangkirai (*), Merbau
 Durable  30-50 Camphor, Kempas
 Moderately Durable  15-25 Nyatoh, Kempas
 Non-Durable 5-10  Coconut wood
 Perishable  less than 5 We do not use

(*) Bangkirai heartwood or a mix of heartwood and sap wood, the latter including with our special in-house developed protection system is not susceptible to termites. Well maintained the wood will last 100+ years


One of the most frequently asked questions we get is what is the life expectancy of a timber frame home from prefabricated elements. 

The classic timber frame homes have lived whole centuries. The current quality timber frame houses and the prefab houses as their successors are based on the advantages and durability of a range of materials, so the house as a system can function safely for a long period of time

A research conducted by the University of Leipzig in 2002 shows that traditionally built houses from brick are no better regarding durability and life expectancy than timber frame homes. According to the research for the last 40 years the characteristics and elements of timber prefab houses are significantly improved and they are good to inhabit at least 80 years - depending on the maintenance performed by their owners. Their technical life with a normal maintenance can be even 150 - 200 years.

In addition to the length of time the wood can physically maintain its structural integrity, there’s also the matter of a wood’s weathering characteristics. Weathering can’t be as clearly expressed in a single number or measurement, but overall, woods with good weathering characteristics exhibit limited photo-degradation (caused by UV rays in sunlight), as well as above-average resistance to contraction and expansion, warping, and surface checking due to seasonal changes in temperature and humidity.
Because of this vague definition, only woods that have notably good weathering characteristics are used by us. Bangkirai ane Merbau are noted for both its excellent durability and its superb weathering characteristics.

Reviews from Prefab World Bali

"Of so many websites I had visited, yours is one of the best designed and focused. I am truly surprised at the amount of information regarding your company's expertise and experience that you willingly publicized online.

It's little wonder that copy cats are lining up, salivating to emulate your achievements. However they will never be able to muster the expertise in both structural and architecture knowledge that is endowed in the educational background.
Few also will be able to emulate your:
o  business integrity (which is extremely rare nowadays)
o  passion to experiment on what works best and continually incorporating them into your design and end products and
o  using the highest quality raw materials and their treatments thereof to ensure a defect free building that will withstand the     test of time.
Little wonder that your company is the foremost prefabricated wooden house company in Indonesia.
Keep up the great work and may I wish you the very best for years to come
Leong Yue Peng, Malaysia."
